We were asked to design and build what for all intents and purposes is an "outdoor living room" for a classic Winnebago RV. The program called for a large covered deck, a level covered parking spot for the RV, and two saddlebags, one housing a composting toilet and the other an outdoor shower. Out of this stripped down program we fashioned a classic Texas pipe-barn structure crafted from used oil-pipe with a corrugated Galvalum roof.
Wood clad saddlebags and tilt-up polygal clad wall panels enclose the sides of the structure providing privacy and a bit more shelter, with the third wall closed off by the RV. The whole ensemble sidles up to two nice specimen live oaks, which provide further shade to the uncovered portion of the deck.
